Simple CSS Text Formatting Question

I'm trying to get some header text to look right in CSS.
The closest example would be the header text on the Symantec homepage which says... Home & Office, Small & Mid-Sized Business, Enterprise Solutions etc

I tried this but it doesn't even look the same...any help would be appreciated.
.myheadertext{
      font-family: Arial, Helvetica, sans-serif;
      font-size: 1.2em;
      font-weight: 700;
      color: #333333;
      letter-spacing: -1px;
      height: 10.1pt;
}
